ARTIFICIAL-TOOTH PLATE.

SPECIFICATION forming part of Letters Patent No. 494,393, dated March28, 1893.

Application filed January 17, 1893- Serial No. 8,696. (No model.)

To all whom it may concern:

Be it known that I, JOHN CHARLES STAPLE- TON, a citizen of the UnitedStates, residing at Washington, in the District of Columbia, haveinvented certain new and useful Improvements in Plates for ArtificialTeeth; and I do declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same, reference being hadto the accompanying drawings, and to the letters of reference markedthereon, which form a part of this specification.

My invention has relation to artificial teeth plates, and moreparticularly to a novel means of securing the plate in place without theaid of a vacuum or clamps, clasps or the like, and the object of myinvention is to provide a means for securing said plate in place in acomfortable, convenient and agreeable manner, without the hard rubber ormetal coming in contact with and irritating the gums or roof of themouth, and to these ends the novelty consists in the construction,combination and arrangement of the same as will be hereinafter morefully described and particularly pointed out in the claim.

In the accompanying drawings the same letters of reference indicate likeparts of the invention.

Figure 1 is a perspective view of an upper set of teeth mounted on aplate and having my improved suction pad secured thereto, and Fig. 2 isa longitudinal section on the line a-a of Fig. 1.

A represents the plate proper, and it is provided with the teeth, B,which, of course, may be complete or only a partial set, as required.

O is a flexible pad, preferably of silk or similar fibrous material, andit is secured to the top of the plate, A, by a stitching or a suitablecement, so that its upper face will come into intimate contact with theroof of the mouth, so that, when moistened and suction applied to thesame through the medium of the tongue and lips, theair is exhaustedbetween the top of the plate, the pad and the roof of the mouth, therebyallowing the pad to intimately fit the roof of the mouth in a pleasantand comfortable manner and at the same time securely hold the plate inplace, without having the metal or other material of which the plate maybe made to come into contact with the mouth.

The material of which the plates are usually made is eithera meta1,suchas gold, silver or platinum, or a substance like rubber or celluloid,and in many instances the hard material coming in contact with thetender parts of the mouth causes great discomfort and inconvenience, ifnot irritation and pain, all of which is obviated by the use of my soft,flexible pad.

The construction of pad itself and manner of securing it to the Plateare matters which may be varied to suit individual cases withoutdeparting from the spirit of my invention, and in some instances I havefound the device to work perfectly without even securing the pad to theplate.

Having thus fully described my invention, what I claim as new anduseful, and desire to secure by Letters Patent of the United States, 1s

As an improved article of manufacture a dental plate havinga smoothcrown and provided with a suction pad corresponding in size and shape tothe crown of the plate substantially as shown and described.

In testimony whereofI affix my signature in presence of two witnesses.

JOHN CHARLES STAPLETON.-
